There are a lot of optical devices that allow you to see in the dark. However, the most common and popular among them can definitely be called night vision binoculars. After all, this device, unlike the monocular, is equipped with two electron-optical converters. From each of them, the image falls into one of the eyepieces, therefore it is possible to obtain a stereoscopic image.
Appointment
For hunters, this attribute is indispensable. Night vision binoculars are designed to observe objects in the dark from close range, so for them it doesn’t matter how much it magnifies objects. The multiplicity is small or even zero. The increase in the distance from which it is possible to conduct effective observation depends on the power of the device itself, on whether there are additional illumination functions in the binoculars, on the degree of illumination of the terrain naturally and other similar conditions. It is clear that with a light background, for example, when objects are in the snow, in the light of the moon, observation through binoculars of night vision is much easier.
Principle of operation
The operation of the device is based on the ability to increase the brightness of an object, in the range of the visible and near infrared spectrum, in multiple sizes. Depending on the technical characteristics and design features, night vision binoculars are divided into active and passive. For passive binoculars, outgoing light is sufficient. Active are equipped with additional illuminators, which in the case of a lack of reflected light produce illumination.
Binocular selection
The conditions in which the use of such an optical apparatus as night vision binoculars for hunting is required are very different, including very difficult. This may be precipitation, poor natural light at night, the inability to fix binoculars. Therefore, taking into account the peculiarities of the use of devices in adverse conditions, different types of binoculars are created.
In order to choose the right night vision binoculars for hunting, you need to clearly know the features of each species that exists on the market. It is clear that in the first place the choice of binoculars is affected by the optical aperture value. It is precisely the possibility of amplifying even the smallest amount of light captured by binoculars that allows it to be used in the darkest time of the day.
The optimal combination of multiplicity and diameter is 7x42 and 7x50. To amplify the light emanating from such natural sources as stars, the moon, as well as reflection from surfaces, an electron-optical converter installed in binoculars is used.
From several types of image intensifier tubes, two main types can be distinguished. The binoculars of the first generation, which can also be active and passive, are characterized by the presence of a large diameter of the lenses, which allows to obtain a completely readable image at the output. A distinctive feature of the first generation of night vision devices is the presence of a clear image only in the center. As you approach the edges, it becomes blurry. In addition, if a strong light source, such as a lamp, enters the field of view of the binoculars, the entire image is illuminated.
Active night vision binoculars with special infrared illumination can be used in complete darkness, even without the presence of any additional light sources. The main disadvantage of this type of devices is their high degree of vulnerability and the possibility of slight damage.
In the second generation, binoculars equipped with electron-optical converters amplify the residual light several times more than the first generation. Such devices are used, as a rule, for professional or semi-professional purposes. The quality of the second generation night vision binoculars is slightly higher.
In addition to the main characteristics, if you choose night vision binoculars (reviews of experienced hunters emphasize this), you need to pay attention to such parameters as a robust body, suitable weight, and ease of use. In addition, it should be borne in mind that binoculars can be placed on tripods, so when choosing a night vision device, this parameter should also be taken into account.
At present, there are 3rd generation night vision devices, but they are intended purely for the military.
All About Yukon Night Vision
Yukon Advanced Optics is one of the largest companies that produces and sells optical equipment such as a monocular, telescope, thermal imager, sight, laser rangefinder equipment and night vision binoculars. Yukon is relatively young, established in the USA (Texas) at the end of the last century, in 1994. The engineers of this structure are using the latest technology to develop products.
Advantages of night vision devices "Yukon"
The purpose of these devices is to assist in the observation and orientation of the terrain in the dark. They are endowed with the ability to inspect the territory in pitch darkness and at a great distance, because they are equipped with IR illuminators.
These special devices can be an element of equipment (this is a universal module on which attachment heads are provided on the head) or can be mounted on a portable tripod.
In any company store you can buy auxiliary accessories and equipment for such high-quality optics.
Night Vision Priorities
- A wide viewing angle allows you to track the movement of objects in an open area and in urban environments;
- the likelihood of photographing and video recording of what is happening in the dark in the study area;
- the possibility of its use in adverse weather conditions;
- some models are able to work with short-term immersion in water to a depth of one meter;
- have the compactness and light weight necessary for long-term field operation.
Price
Models of the Yukon company are provided in a wide assortment for any wallet. A quite democratic option today is night vision binoculars, the price of which varies in the range from 2000 to 20,000 rubles.
Before purchasing the device, it is important for the buyer to familiarize himself with the characteristic features of its operation, maintenance, and possible repair by consulting the personnel of a specialized outlet.
